googleCalendar.listEventInstances expands one recurring parent event into its individual occurrences. Use the parent series ID, not an occurrence ID.
Example
Inputs
Provideevent. calendar defaults to primary. Optional pageToken, includeDeleted, timeMin, and timeMax constrain the page. originalStart selects the occurrence identified by its original schedule, even if it moved; use an RFC 3339 timestamp for timed events or YYYY-MM-DD for all-day events. maxResults accepts 1–2,500, maxAttendees limits attendees returned per occurrence, and timeZone selects the response timezone. Second argument { account } selects the Google Account.
Output
Returns the same event page as List events. Each occurrence normally includesrecurringEventId and originalStart. Use nextPageToken to continue.
